90 rpm on a stationary bike is relatively fast.
90 rpm on a stationary bike is pretty fast. Most people can only sustain that kind of speed for a short period of time. If you’re looking to get a good workout in, you should try to maintain a speed of around 60-70 rpm.
How Many Miles Per Hour Is 90 Rpm On A Stationary Bike?
90 rpm on a stationary bike is equivalent to 15 miles per hour.
How many miles per hour is 90 rpm on a stationary bike?
To find out how many miles per hour is 90 rpm on a stationary bike, you need to know the circumference of the bike’s wheels. The average wheel circumference for a stationary bike is 26 inches. To find the miles per hour, you need to divide the rpm by the circumference and then multiply by 60. Here’s the equation:
Miles per hour = (rpm ÷ circumference) x 60
For our example, that would be:
Miles per hour = (90 ÷ 26) x 60
That comes out to 21.2 miles per hour.
Now, let’s say you’re on a stationary bike and you want to know how fast you’re going. You can use the above equation to figure it out. Just multiply the rpm by 2.14 (this is the number of rotations per minute that equals one mile per hour) and then divide that by the circumference of the wheels.
For example, if you’re on a bike with 26-inch wheels and you’re pedaling at 90 rpm, you’re going 21.2 miles per hour.
How Many Laps Per Minute Is 90 Rpm On A Stationary Bike?
90 rpm is one and a half laps per minute on a stationary bike.
If you’re like most people, you probably think of “rpm” as “revolutions per minute” – meaning, how many times the pedals of a stationary bike go around in one minute. But “rpm” on a stationary bike can also mean “laps per minute,” which is a measure of how far you’re pedaling in one minute.
For example, if you’re pedaling at a moderate pace on a stationary bike and your pedometer says you’re going at 90 rpm, that means you’re pedaling 90 laps per minute. If you’re pedaling at a very slow pace, you might only be going 30 rpm. And if you’re pedaling very fast, you might be going 120 rpm or more.
Why is it important to know how many laps per minute you’re pedaling?
Because it can help you gauge how hard you’re working out. If you’re trying to pedal at a certain heart rate, for example, you might need to pedal faster or slower to reach your target.
Here’s a quick way to calculate laps per minute:
First, find out the circumference of the bike’s wheel. To do this, measure the distance around the outside of the wheel (from one tire to the other) with a tape measure.
Next, divide the circumference of the wheel by the number of rotations per minute (rpm).
For example, let’s say the circumference of the wheel is 2 feet (24 inches). And let’s say you’re pedaling at 90 rpm.
To find out your laps per minute, simply divide 24 by 90. This gives you 0.267 laps per minute – or, in other words, you’re pedaling just over a quarter of a lap per minute.

Remember, the next time you jump on a stationary bike, that “rpm” can mean either “revolutions per minute” or “laps per minute.” Knowing which one you’re looking at can help you better gauge the intensity of your workout.
